To analyze a thing from different angles, it is very likely to find different characteristics and characteristics. In the following, in order to better describe the magnetism, we analyze it from as many angles as possible. From the perspective of kinetic energy: a magnet is an ultrasonic transducer. That is, a machine that replaces electromagnetic energy with mechanical energy. This is also the essential characteristic of magnets.
Look at it from the perspective of mechanical equipment: magnets are also one of the energy sources that provide postures for mechanical equipment. Let's take a look at the mechanical energy sources in addition to magnets, such as motors, pneumatic management systems, and hydraulic press management systems (further, pneumatic or hydraulic presses use air pumps and gas filters, and the power energy is still provided by motors), and ideas ( Whether it is a car, an airline, or an aerospace industry, the idea is to convert chemical energy into mechanical energy), it is very likely to see that the mechanical energy source that is likely to be used by people is public, and it is constrained by the application scene. Most of the industrial chain or civilian use a large number of motors or motors. This is probably also due to the convenient use and transmission of electromagnetic energy. Most of the electrical energy storage methods are converted into electromagnetic energy for use. However, no matter which type of motor immediately outputs electric energy, the method is to rotate, and replacement distribution must be installed in the place where translation is required. In this way, the legal effect of the mechanical equipment of the landing management system is greatly enhanced; because of this, the translational speed frequency output by the gear transmission in the end has no choice but to move forward, and the mechanical equipment of the motor and the replacement distribution itself is not so simple in structure, which prompts Magnets have the advantage of being irreplaceable when the translation spacing is not very large and the translation speed frequency has certain requirements.
From the perspective of electrical equipment: the magnet is a large objective load component. Whether it is a DC electromagnet or an interchangeable magnet, it is all produced by an electromagnetic coil and an iron core, and this type of structure determines its inductor characteristics. The more turns, the thicker the iron core, the larger the inductor, the greater the energy storage technology, the greater the output energy, and the longer the time to take care of the posture. The bigger it is, the less strong the magnet works. For the interchangeable magnet, the vortex will cause severe iron loss in the iron core, so the iron core of the interchangeable magnet is made of block accumulation to reduce the vortex, which is also the appearance of the interchangeable magnet. The reason for the square. For the DC electromagnet, the current will slowly warm up to the rated voltage when plugged in, which is the reason for taking care of the existence of time. When the power is turned off, the inductor is charged and discharged in the opposite direction, resulting in a high voltage in the opposite direction, which affects the contact point of the power switch. Or the switching power supply has a reverse impact, and when the DC output power or electromagnetic induction is relatively large or the posture is repeated, it is necessary to add a freewheeling two-tube or a maintenance component that accepts the current in the reverse direction.
From a control point of view: a magnet is a state-controlled component. Due to the simple structure of the magnet, there is no way to ensure the control of the output amplitude, direction and speed during the magnet theme activity. Even if the closed-loop control is used to carry out real-time control, the adverse effects of the control are all good, and the magnet's control of the state is very obvious, the timely and homing, and the two state directions after frequent repetition are basically not easy to cause changes.
